Serial No. 87,408.

An object of my invention is to provide a metal tile for use in concrete floor construction and a simple and inexpensive means for mounting and positioning said tiles.

Another object is to provide a mounting means which is inexpensive of manufacture and simple of application.

Another object is to provide a metal tile and mounting means therefor which will permit ready removal of the tiles after the concrete floor has been poured and has become set.

Another object is to provide a mounting means for the purpose stated which is adapted for use with tiles of various sizes.

These and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which Fig. 1 is a fragmental perspective view of a structure embodying the tile and mounting means of my invention prior to the pouring of concrete.

Fig. 2 is a similar view showing a modified application of the device of my invention.

The metal tiles 8 are of any approved shape and are provided with sides 9 having straight bottom edges 10. The mounting means comprises angle strips 11, the sides 12 and 13 of which may be at right angles to one another. As shown in Fig. 1, a suitable supporting structure comprising shoring 14, stringers 15 and soilits 1G is erected. The angle strips 11 which may be of light gauge metal, are then secured in alignment upon the opposite sides of the soilits 16 by means of nails 17. The tiles 8 are then positioned between the angle strips 11 by seating the opposite longitudinal edges 10 of a given tile upon adjacent soiiits, with the sides 9 of said tile in abutment with the upstanding sides 12 of the angle strips. The concrete is then poured over the tiles and the space between the outer faces of the side walls 9 of the tiles is filled with concrete to form beams. It will be readily understood that suitable reenforcing elements may be positioned between adjacent tiles where required. After a floor has been poured and set, the temporary supporting structure is removed whereupon the soffits 16 will be removed from the beams at which time the longitudinal edges 10 of the tile will be exposed rendering said tiles readily accessible for removal and permitting them to be used again.

. As shown in Fig. 2, the angle strips 11 are positioned with a free edge disposed toward the edge of a soflit 16 and the upstanding side disposed farthest from the edge of said sofiit.

In this structure, the opposite sides 9 of a,. given tile have their longitudinal edges 10 seated upon the upper or inner face of the sides 12 of the angle strips 11 with the outer faces of the sides 9 of the tile in abutment PATENT oF ice WILLIAM M.

strips. When a concrete floor has been poured and has become set upon a supporting structure such as shown in Fig. 2, .the shoring 14 and stringers 15 may be removed whereupon the sleepers 16may be pulled,

down, leavingthe edges 10 of the tiles ex posed and thus facilitating removal of the tiles. 1

It should be noted that in each of the structures described, the angle strips 11 will remain secured tothe soflits 16 and will be removed therewith so that the angle strips may also be used repeatedly. The angle strips ll'being light and easy to handle eliminates considerable labor and difliculty in aligning.

and positioning thetiles. The operation of constructing a floor with the tile and angle strip material of my invention consists in simply providing guide lines along the soffits and nailing the angle strips along the guide line after which the tiles may be readily dropped into place. The upstanding side of the angle strips not only positions the sides of the tile, but also precludes spreading there- 5? mounting strips on the temporary support structure, the angle strips each having an upwardly extending arm, the upstanding arms being disposed alternately on opposite sides of the rows of strips, whereby there arepro vid'ed opposed pairs ofupstanding arms, and

inverted U shape tiles having the .endsof,

their armsreceived between opposed pairs of upstanding arms, whereby a mold for con crete is formed and in which mold the strips are exposed to theconcrete mass and the ends of the inverted U shape tiles areprotected from contact with the concrete mass.

tiles forming joist molds between them, the

outer edges of said-planks against which the tiles engage and which hold and position the latter, said planks and strips being removable as a unit after the concrete has set.

In testimony whereof, I have hereunto subscribed my name this 5th day of February,
